Abstract: The present invention provides a substrate for a secondary battery electrode having excellent bonding strength of a sintered porous metal to a ground metal plate so that the sintered porous metal does not peel off from the ground metal plate when the substrate for a secondary battery electrode is rolled up and fixed into a cylindrical battery. For this purpose, a layer of metal having a melting point lower than that of the ground plate is formed at least on one side of the ground plate, and a porous layer is formed by forming a layer of powdered metal having a melting point higher than that of the layer of metal on the layer of metal and sintering the powdered metal at a temperature not less than the melting temperature of the layer of metal and not more than those of the ground plate and the powdered metal. Also, at least one side of the ground plate is boronized, and a porous layer is formed by forming a layer of powdered metal which is eutectically alloyed with boron on the boronized layer, and by sintering the powdered eutectic alloy at a temperature not less than the melting point of the eutectic alloy and not less than that of the ground plate and the powdered eutectic alloy.

Title: Apparatus and method for scale factor stabilization in interferometric fiber optic rotation sensors
Inventor: GOLDNER ERIC LEE
IPC: G01C19/72
Filed: 1998-06-08
Abstract: A fiber optic rotation sensor system having improved scale factor stability includes an optically pumped gain fiber arranged to provide optical signals to an integrated optics chip connected to a fiber optic sensing coil. An optical coupler receives optical signals from the gain fiber and provides the optical signals to an optical fiber. The optical fiber is arranged to guide optical signals from the optical coupler along an optical path toward the integrated optics chip such that optical signals from the gain fiber are input to the fiber optic sensing coil to form counter-propagating waves therein. The counter-propagating waves traverse the sensing coil and then combine in the integrated optics chip to form a gyro output signal. A depolarizer is placed in the optical path between the first optical coupler and the integrated optics chip to prevent random changes in the state of polarization of optical signals propagating between the gain fiber and the integrated optic chip.

Abstract: A portable hand-held manually operated dry printing apparatus comprises a frame structure, a ribbon holder mounted on the top portion of the frame structure, a dry printing unit mounted on the lower portion of the frame structure and comprising a die member and a heating device for heating the die member, two handles respectively mounted on the two sides of the frame structure, and a ribbon guiding system for guiding the ribbon from the ribbon holder along a path extending between the die member and the surface on which dry printing is performed. Each handle is spaced apart from a portion of the dry printing apparatus heated by the heating device to define an air passage between the handle and the surrounding heated portion, to thereby ventilate an inner face of the handle and prevent this handle from being heated. The ribbon guiding system comprises a generally rectangular bottom plate defining a window and two end notches for guiding the ribbon in front of the window. This generally rectangular bottom plate is mounted to the frame structure through a pair of spring-biased sliding posts sliding on the frame structure against the force exerted by helical springs to apply the die member to the ribbon through the window and thereby transfer material from the ribbon to the surface on which dry printing is performed. The force exerted by the spring members returning the sliding posts and therefore the die member to their initial rest position after the dry printing operation is completed.

Title: Distributed resistance leadwire harness assembly for physiological monitoring during magnetic resonance imaging
Inventor: HOAR EDWARD F
IPC: A61B5/0408
Filed: 1998-12-09
Abstract: A leadwire harness system is used for recording an electrocardiogram (ECG) during magnetic resonance imaging (MRI). The system includes a set of leadwires each having a nichrome wire helically wound on a bundle of glass or other high strength fibers and surrounded by an insulating jacket to provide for uniformly distributing the high resistance within each leadwire so that the eddy currents generated by the rapidly changing magnetic field are greatly reduced. The set of leadwires are twisted within a surrounding tube of foam insulation. The reduction of the eddy currents dramatically reduces MRI image distortion as well as the potential for localized heating and skin burns under the ECG electrodes used with the harness system.

Title: Axial ejection in a multipole mass spectrometer
Inventor: HAGER JAMES W
IPC: H01J49/42
Filed: 1997-06-02
Abstract: A method of operating a mass spectrometer having an elongated multipole rod set, in which a two-dimensional RF field radially contains trapped ions in a mass to charge range of interest, and in which the ions are contained axially by a barrier field on an end lens and to which a low voltage DC is applied. Trapped ions are axially mass selectively ejected by taking advantage of the mixing of the degrees of freedom induced by the fringing fields and other anti-harmonicities in the vicinity of the end lens. Thus, ions can be mass selectively ejected at the exit end at the same time as ions are being admitted into the entrance end of the rod set, thereby taking better advantage of the ion flux from a continuous ion source. The axial mass selective ejection is performed by applying an auxiliary AC voltage to the end lens, and by scanning either the auxiliary AC voltage or the RF voltage on the rod set. Trapped ions can be concentrated near the exit lens by applying an axial field in the direction of the lens, or can be depleted by applying the axial field in the opposite direction. The axial field can be oscillated to dissociate trapped ions.

Title: System for electronic repository of data enforcing access control on data search and retrieval
Inventor: BACHA HAMID
IPC: G06F21/62
Filed: 1998-12-23
Abstract: When an electronic document is made available for review by other entities, it is often convenient to store the document in a repository or database managed by a third party. A  system is provided in which the entities authorized by the originator of a document to access it in the data repository, are able to securely search for the document filed with a third party repository without having to trust the administrator of the repository to provide accurate information on their access privileges. The document originator, the repository administrator and all entities with access privileges to data in the repository have vault environments which are secure extensions of their respective work spaces. The vault of the document originator maintains an access control list (ACL) for each document it has deposited with the repository. The vault of each entity with access privileges to any documents in the repository maintains a capability list of the entity's access privileges to all of the documents stored in the repository. The entity itself maintains proof of the latest version of its capability list on its own desktop. When the ACL for a document is updated in the document originator's vault, the originator's vault determines what entities are affected by the change, and communicates the change to the affected entities' vaults. Each vault updates its own capability list, and at the first available opportunity, updates the proof of the latest version of the capability list on the entity's desktop.

Likewise the slatted portion includes a right and left sides which include right and left channels which align with the inner channels on the top and bottom members. Right and left side rails snap fit into the three sections holding them together. The inner wall of the rails snap into the inner channels and the channel in the slatted portion. The inner walls of the side rails include upper arcuate lips that extend over the top edges of the side walls of the top, bottom and slatted sections. The outer wall of each rail includes an L-shaped projection which fits within the outer channels in the flanges. The shutter can be adjusted by removing sections of the slatted portions along pre-formed score lines and then cutting rails to the desired size. Shutters are then assembled and mounted to a building surface. The inner and outer channels prevent the flanges from spreading out, and standing ribs keep the rail from collapsing when screwing down, providing a natural appearance. The configuration of the inner channels facilitates the ease of assembly.
